無法更新產品表獲取您必須使用「set」方法來更新條目

Question

即時通訊仍在學習codeigniter，並提出了一個問題。那是 您必須使用「set」方法更新條目。

我想更新一個表：下面包含product_name，product_desc等欄的產品是我的控制器，視圖和模型..我無法弄清楚我做錯了什麼..我總是檢查出print_r（$ array） ;它給了我一個空陣列...雖然我確實在鏈接上輸入字段中顯示產品詳細信息：ci/index.php/admin/product/1 ..

將視圖的一半代碼視爲視圖代碼是長..

控制器：

// ****爲編輯產品**** //

public function edit_products(){ 


        $data = array ('product_name'=>$this->input->post('product_name'), 
        'product_desc'=>$this->input->post('product_desc'), 
        'product_stock'=>$this->input->post('product_stock'), 
        'product_sku'=>$this->input->post('product_sku'), 
        'inventory_date'=>$this->input->post('inventory_date'), 
        'product_price'=>$this->input->post('product_price'), 
        'featured_product'=>$this->input->post('featured_product'), 
        'best_seller'=>$this->input->post('best_seller'), 
        'brand_id'=>$this->input->post('brand_id'), 
        ); 

        $upd_pr = $this->mainmodel->update_product($_POST); 
        if($upd_pr){ 
         $this->session->set_flashdata('messages', 'Updated Sucessfully'); 


         redirect('admin/editing_products'); 

          }else{ 
         $this->session->set_flashdata('error', 'Updation Failed'); 
          redirect('admin/editing_products'); 
           } 
      } 



    public function editing_products(){ 


$data['product']=$this->mainmodel->set_pro2(); 
     //$data['images'] = $this->products->images($id); 
     $data['content']='admin/edit_products'; 

     $this->load->view('admin/main',$data);  
      } 

---

型號：

/*for update Product*/ 
    public function update_product($array){ 

     extract($array); 


     //print_r($array); 
     //die; 

    $this->db->update('product',array('product_name'=>$product_name,'product_desc'=>$product_desc,'inventory_date'=>$inventory_date,'product_price'=>$product_price,'featured_product'=>$featured_product,'best_seller'=>$best_seller,'brand_id'=>$brand_id)); 

$this->db->update('product'); 



        return ; 
    } 


function set_pro2(){ 
     $q = $this->db->query('SELECT * FROM product,product_image,category_product WHERE product.product_id = category_product.product_id AND product.product_id = 1 LIMIT 1'); 

如果（$ Q-> NUM_ROWS（）> 0）{

 foreach($q->result() as $row){ 

     $data[] = $row; 

     } 
     return $data; 
     } 
}

在某些情況下笨更新/插入要求this->db->set如果在數組中。我也不建議將兩個db->update放置在您添加到模型上的同一張桌子上。

更新

// $brand_id = 0, $data are from the edit function on controller 
public function name($brand_id = 0, $data) { 
$product_name = $this-input->post('product_name'); 
$product_desc = $this-input->post('product_desc'); 
$inventory_date = $this-input->post('inventory_date'); 
$product_price = $this-input->post('product_price'); 
$featured_product = $this-input->post('featured_product'); 
$best_seller = $this-input->post('best_seller'); 

$data = array(
'product_name'=> $product_name, 
'product_desc'=> $product_desc, 
'inventory_date'=>$inventory_date, 
'product_price'=>$product_price, 
'featured_product'=> $featured_product, 
'best_seller'=> $best_seller, 
'brand_id'=> $this->uri->segment(what_ever) 
); 
$this->db->set($data); 
$this->db->update('product'); 
} 

或插入

$data = array(
'product_name'=> $product_name, 
'product_desc'=> $product_desc, 
'inventory_date'=>$inventory_date, 
'product_price'=>$product_price, 
'featured_product'=> $featured_product, 
'best_seller'=> $best_seller, 
'brand_id'=>$brand_id 
); 
$this->db->set($data); 
$this->db->insert_id(); 
$this->db->insert('product');

個

路由集$route['function/edit/(:any)'] = 'folder/products_list/edit/$1';

如果需要更新您需要設置一個叫做編輯功能的

型號產品獲取URI段

public function model_get_products() { 
return $this->db->get($this->db->dbprefix . 'products')->result_array(); 
} 

控制器幫助http://www.codeigniter.com/user_guide/libraries/uri.html

public function edit() { 
    Form validation 
    $this->load->library('form_validation'); 

    $this->form_validation->set_rules('what ever'); 

    if ($this->form->validation->run() == TRUE) { 
    $this->load->model('folder/model_update_product'); 

    //Example uri segment admin/product_list/edit/id_number $this->uri->segment('4') 

    $this->model_update_product->name($this->uri->segment('what_ever_is'), $this->input->post()) 

    redirect('function/product_list'); 

    } else { 
    // Load Your Form View i.e. $this->get_form(); 
    } 
} 

public function index() { 

$this->load->model('folder/model_get_products'); 

$results = $this->model_get_products->get(); 

$data['products'] = array(); 

//Example uri segment admin/product_list/edit/id_number $this->uri->segment('4') 

// Add What Else You Need to here and then you can add it to view 

foreach($results as $result) { 
    $data['products'][] = array(
    'brand_id' => $result[brand_id], 
    'edit' => site_url('controller_name/edit'). '/' .$result[brand_id] // site_url must match what you set in routes for edit. 
    ); 
} 

return $this->load->view('folder/products_list', $data); 
} 

public function get_form() { 
//Example uri segment admin/product_list/edit/id_number $this->uri->segment('4') 

// Make sure you set another model function in your get model where can get by id. 

$product_info = $this->get_products_by_id->get($this->uri->segment('4')); 

    $product_name = $this->input->post('product_name'); 

    if (isset($product_name)) { 
    $data['product_name'] = $product_name; // for name="" in input 
    } elseif (!empty($product_info)) { 
    $data['product_name'] = $product_info['product_name']; // for value="" in input 
    } else { 
    $data['product_name'] = ''; 
    } 

    $this->load->view('folder/product_form', $data);
